What is the value of the coriolis force at the equator?

The direction of rotation changes between the two hemispheres. The Coriolis effect is greatest at the poles and zero at the equator because of the earth's spherical shape. read more

Coriolis force is expressed as, F=2VΩsin A. Where V is velocity, Ω is angular velocity and sinA is latitude. At equator, sinA=sin0°=0. That's why at equator. F=0. As a result coriolis force is absent at the equator and at poles equator sinA is sin90° ,then the coriolis force is highest. read more

At the equator, [itex]\boldsymbol{\omega}\times \mathbf v[/itex] is directed purely upward. It has zero horizontal component. So to an atmospheric scientist, the Coriolis force is zero at the equator because they use a different definition of Coriolis force than the definition used by physicists. read more
